1 | Kernel driver abituguru3 | ||
2 | ======================== | ||
3 | |||
4 | Supported chips: | ||
5 | * Abit uGuru revision 3 (Hardware Monitor part, reading only) | ||
6 | Prefix: 'abituguru3' | ||
7 | Addresses scanned: ISA 0x0E0 | ||
8 | Datasheet: Not available, this driver is based on reverse engineering. | ||
9 | Note: | ||
10 | The uGuru is a microcontroller with onboard firmware which programs | ||
11 | it to behave as a hwmon IC. There are many different revisions of the | ||
12 | firmware and thus effectivly many different revisions of the uGuru. | ||
13 | Below is an incomplete list with which revisions are used for which | ||
14 | Motherboards: | ||
15 | uGuru 1.00 ~ 1.24 (AI7, KV8-MAX3, AN7) | ||
16 | uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO) | ||
17 | uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8) | ||
18 | uGuru 2.3.0.0 ~ 2.3.0.9 (AN8) | ||
19 | uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X, | ||
20 | AW9D-MAX) | ||
21 | The abituguru3 driver is only for revison 3.0.x.x motherboards, | ||
22 | this driver will not work on older motherboards. For older | ||
23 | motherboards use the abituguru (without the 3 !) driver. | ||

30 | Module Parameters | ||
31 | ----------------- | ||
32 | |||
33 | * force: bool Force detection. Note this parameter only causes the | ||
34 | detection to be skipped, and thus the insmod to | ||
35 | succeed. If the uGuru can't be read the actual hwmon | ||
36 | driver will not load and thus no hwmon device will get | ||
37 | registered. | ||
38 | * verbose: bool Should the driver be verbose? | ||
39 | 0/off/false normal output | ||
40 | 1/on/true + verbose error reporting (default) | ||
41 | Default: 1 (the driver is still in the testing phase) | ||
42 | |||
43 | Description | ||
44 | ----------- | ||
45 | |||
46 | This driver supports the hardware monitoring features of the third revision of | ||
47 | the Abit uGuru chip, found on recent Abit uGuru featuring motherboards. | ||
48 | |||
49 | The 3rd revision of the uGuru chip in reality is a Winbond W83L951G. | ||
50 | Unfortunatly this doesn't help since the W83L951G is a generic microcontroller | ||
51 | with a custom Abit application running on it. | ||
52 | |||
53 | Despite Abit not releasing any information regarding the uGuru revision 3, | ||
54 | Louis Kruger has managed to reverse engineer the sensor part of the uGuru. | ||
55 | Without his work this driver would not have been possible. | ||
56 | |||
57 | Known Issues | ||
58 | ------------ | ||
59 | |||
60 | The voltage and frequency control parts of the Abit uGuru are not supported, | ||
61 | neither is writing any of the sensor settings and writing / reading the | ||
62 | fanspeed control registers (FanEQ) | ||
63 | |||

65 | include the output of: "dmesg | grep abituguru" | ||
